HTTP Proxy Authentication  Locate

A WSO2 SOA Enablement Server client may need to access a service via a proxy server requiring authentication. The current version of WSO2 SOA Enablement Server lets the client authenticate through the proxy server with basic authentication as specified in RFC 2617.

Entering a username and password for HTTP(S) proxy authentication is very simple. Just specify the system properties http.proxyUserName (https.ProxyUserName) and http.proxyPassword (https.ProxyUserName). For example:

java "-Djava.security.auth.login.config=%WASP_HOME%\conf\jaas.config" "-Dhttp.proxyUserName=Mustafa"

"-Dhttp.proxyPassword=open sesame" demo.hello.HelloWorldClient

Lookup operations using ServiceClient.create(wsdlURL, contextData) and ServiceClient.createProxy(Class)) may also specify a username and password for proxy authentication. If the parameter contextData contains security properties defined in ServiceClientContext and WaspSecurity, these properties will be used and take a higher priority than the properties defined in the system properties. Example 7 shows how to look up the Deploy service if a client runs via a proxy requiring authentication:
